Question

Which of the following is NOT a long-distance transport pathway in plants?

B VENKAT · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
	**Primary Concept**: Plant Transport Systems
	**Related Topics**: Xylem, Phloem, Apoplast, Symplast, Transpiration, Translocation
	**Prerequisites**: Basic plant anatomy and physiology
## SOLUTION PATHWAY
**Given Information**:
	We need to identify which of the given options is NOT a long-distance transport pathway.
**Method & Steps**:
	1. **Understanding Long-Distance Transport**: Long-distance transport refers to the movement of substances over long distances within the plant, typically from roots to shoots or vice versa.
		Reasoning: This usually involves specialized vascular tissues.
	2. **Analyzing Xylem and Phloem**: Xylem and phloem are the primary vascular tissues responsible for long-distance transport.
		Working: Xylem transports water and minerals from roots to shoots. Phloem transports sugars (produced during photosynthesis) from source to sink tissues.
		Key Point: Both xylem and phloem are involved in long-distance transport.
	3. **Evaluating Apoplast and Symplast**:  Apoplast and symplast are pathways for short-distance transport, specifically for lateral movement of water and solutes within a tissue or between adjacent cells.
		Result: Apoplast refers to the continuous space outside the plasma membrane, while symplast refers to the continuous cytoplasm connected by plasmodesmata.
		Verification: Apoplast and symplast are essential for short-distance transport but are not the primary pathways for long-distance movement across the plant.
 ## OPTION ANALYSIS
[A] :x: Xylem is responsible for the long-distance transport of water and minerals from roots to shoots.
[B] :x: Phloem is responsible for the long-distance transport of sugars and other organic molecules throughout the plant.
[C] ✓: Apoplast is involved in short-distance transport, not long-distance transport.
[D] :x: Symplast is involved in short-distance transport, not long-distance transport.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing apoplast and symplast with xylem and phloem: Remember that xylem and phloem are tissues, while apoplast and symplast are pathways within tissues.
		2. Overlooking the 'NOT' in the question: Carefully read the question to ensure you are selecting the option that does not fit the criteria.
	**Quick Tips**:
		1. Xylem transports water and minerals (think 'W' for water and 'X' for xylem).
		2. Phloem transports photosynthates (think 'P' for phloem and 'P' for photosynthates).
